子午线轮胎工艺流程
    英文回答：
    Submeridian Tire Manufacturing Process.
    1. Raw Material Preparation.
    Natural rubber is obtained from rubber trees and synthetic rubber is produced from petrochemicals.
    Carbon black is added to enhance strength and durability.
    Other ingredients such as silica, oils, and antioxidants are incorporated to improve performance and longevity.
钢丝轮胎    2. Mixing.
    The raw materials are combined and thoroughly mixed in a banbury mixer.
    The mixing process helps to distribute the ingredients evenly and create a homogeneous compound.
    3. Extrusion.
    The mixed compound is heated and forced through an extruder, which shapes it into various components such as the tread, sidewall, and bead.
    4. Calendering.
    The extruded components are passed through a series of rollers to flatten and refine their shape.
    This process helps to create a smooth and uniform surface.
    5. Assembly.
    The different components are assembled together to form the tire carcass.
    The tire is then placed on a building drum and wrapped with a rubberized fabric called the belt.
    6. Curing.
    The assembled tire is placed in a mold and heated under pressure.
    The curing process vulcanizes the rubber, giving it strength and elasticity.
    7. Inspection and Finishing.
    The cured tire is inspected for any defects or imperfections.
    The tire is then trimmed, balanced, and inflated to its recommended pressure.

    1. 原材料准备。
    从橡胶树中获取天然橡胶，合成橡胶由石油化工品制成。
    添加炭黑以增强强度和耐用性。
    添加其他成分（如二氧化硅、油和抗氧化剂）以提高性能和延长使用寿命。
    2. 混炼。
    将原材料混合在班伯里混炼机中充分混炼。
    混炼过程有助于均匀分布成分并形成均匀的化合物。
    3. 挤出。
    加热混合好的化合物，并通过挤出机将其塑造成胎面、侧壁和胎唇等各种部件。
